The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...

Plant-growth-promoting rhizobacteria (PGPR) are associated with plant roots and augment plant productivity and immunity; however, recent work by several groups shows that PGPR also elicit so-called 'induced systemic tolerance' to salt and drought. As we discuss here, PGPR might also increase nutrient uptake from soils, thus reducing the need for fertilizers and preventing the accumulation of ni...

Plant growth promoting rhizobacteria (PGPR) belonging to Pseudomonas spp. are being exploited commercially for plant protection to induce systemic resistance against various pests and diseases. Mixtures of di!erent PGPR strains have resulted in increased e$cacy by inducing systemic resistance against several pathogens attacking the same crop. Seed-treatment with PGPR causes cell wall structural...

Salinity affects plant growth and is a major abiotic stress that limits crop productivity. It is well-understood that environmental adaptations and genetic traits regulate salinity tolerance in plants, but imparting the knowledge gained towards crop improvement remain arduous. Harnessing the potential of beneficial microorganisms present in the rhizosphere is an alternative strategy for improvi...

About 45 bacteria, 9 fungi, 3 yeast, and 1 actinobacterium were isolated from plant tissues of tomato screened for their growthpromoting traits antagonistic activity against damping-off fungus Pythium aphanidermatum. The bacterial isolate, Bacillus pumilus TEB10 exhibited pathogen inhibition about 55 79%, while yeast isolate Candida tropicalis TEY1 showed 30 68% in the dual plate inverted assay...

Abstract The consortium of bacteria that inhabit the rhizosphere, acting as plant growth promoting rhizobacteria is known indigenous rhizobacteria. Rhizobacteria can produce chemical compounds protect plants from pathogens and various plant-disturbing organisms. Optimization yield patchouli be done by utilizing potential derived rhizosphere. This study aims to obtain capable producing secondary...

in order to investigate the effects of seed inoculation with plant growth promoting rhizobacteria (pgpr) on germination components and seedling growth of corn (zea mays l.), a factorial experiment based on randomized complete block design with three replications was conducted at the seed technology laboratory of mohaghegh ardabili university, iran, during 2008. studied factors were: corn cultiv...

The interactive effect of phosphate-solubilizing bacteria and arbuscular mycorrhizal (AM) fungi on plant use of soil P sources of low bioavailability (endogenous or added as rock phosphate [RP] material) was evaluated by using soil microcosms which integrated (sup32)P isotopic dilution techniques. The microbial inocula consisted of the AM fungus Glomus intraradices and two phosphate-solubilizin...
